OK, here's my current problem, which may be due to a vaccum leak.
This is on ECON, at 72 degrees.
Car starts, I soon get heat down at the floor vents.  I'm also
getting cold air from the side dash vents, pretty much all the time.
Some bit of air from the defrost vents too, mostly lukewarm.
The floor vents get hot eventually, not really hot but acceptable.
The drivers side is colder than the passenger side.

After a while, the hot air turns cold/lukewarm and I've got air 
blowing on my feet, as well as from the dash vents.
It used to switch into bilevel, where I would get hot air from 
the center dash vent, a bit from the side dash vents and from the
feet, but it hasn't done that lately.

What is also interesting is that with the system off, I get a little
cold air coming out the dash vents and floor, but I hear a hissing 
sound where the glovebox should be (it's still out).
I don't know if this is normal, or a vac leak (as my mechanic
suspects).

Sorry to bug with this again, but I'm getting very frustrated
about this...
